Patented Feb. 18, 1908.

Application filed January 7. 1907. Serial No- 361.092.

To all whom it may concern:

Be it known that I, IRVING MANDEVILLE, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Clasps; and I do herebydeclare the following to be a full, clear, and eXact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being 'had to theaccompanying drawings, and to letters of reference marked part of thisspecification.

This invention relates to a clasp for jewelry, and is designedparticularly to join the ends of collars, belts and similar articles ofapparel, and lock the article so that its ends will not becomedisengaged without a manual manipulation of the clasp.

The invention consists of two members, one to be sewed on each end ofthe element to be fastened together, and these members are arranged tobe slid together longitudinally, and then be twisted slightly to bringthem in their pro er positions and lock the members against ongitudinalseparation.

The invention is further designed to provide each of the members withprojecting wings or loops for securing them to the ends of strips offabric so that a pull on the strips of fabric will draw the members soas to twist them in their locked positions.

The invention is illustrated in the accompanying drawings, in whichFigure 1 is a view of one member, and Fig. 2 a view of the other member,these views showing the faces of the members that go together. Fig. 3 isan end view of Fig. 1, and Fig. 4 is an end view of Fig. 2. Fig. 5 is aperspective view of the two members separated, but showing them inpositions ready for their assembling. Fig. 6 is a section through thetwo members showing them in their positions for en a ement or disen aement and Fi 7 b b b is a similar view, but showing the members twistedto lock them together.

One member 10 has, on its obverse face, any suitable configuration ordesign, and serves for a cover for the structure when it is claspedtogether. The member 10 has its plate provided with a wing 11 which canbe of any suitable configuration, but is preferably made as in thedrawings, that is in the I nature of a loop. A round bar 12 is mountedon the back of the plate 10 by the ribs 13 which are suitably disposed.The other member comprises a tubular body portion 14 which is providedwith the wing 15, also preferably made in the shape of a loop for thesake of lightness, and the end 16 of the tubular portion 14 is closed tolimit the movement of the second member on the first member 10. Thetubular member has a longitudinal slot 18 which, at the open end,isflared, as at 17, and at points, suitably arranged, are the transverserecesses 19 which open in the slot 18, and the purposes of theserecesses will be described hereinafter.

When the device is to be clasped, the tubular portion 14 is slid ontothe bar 12, the slot 18 receiving the ribs 13, and when the top 16 ofthe tubular member 14 abuts on the end of the bar 12, the ribs 13 are inline with the recesses 19, and the device is in the position shown inFig. 6. When the fabric 20, attached to the two members, is pulled or istightened by its being in place, it acts to draw, by means of the wings11, so that the members assume the position shown in Fig. 7, therecesses 19 receive the ribs 13, and the tubular member 14 cannot beslid off from the bar 12. The device is thus securely locked againstaccidental displacement, and when the article is to be removed, theclasp is grasped, and the wings are manipulated to be out of line and torelease the ribs 13 from the recesses 19, and the two members can thenbe longitudinally slid apart.

Having thus described my invention, what I claim is 1. A claspcomprising a member having inwardly inclined ribs on the back thereofwhereby the member hides the ribs, a bar secured to the ribs, and asecond member comprising a tubular portion having a longitudinal slotand having transverse recesses opening into the slot, the recess beingad apted to receive the ribs of the first member, the clasp whenassembled having the first member disposed to cover the second memberand the bar.

2. A clasp comprising a member,'as 10, having inwardly inclined ribs onthe back thereof, a bar secured to the ribs, a second member comprisinga tubular portion having a longitudinal slot and having recesses openinginto the slot, the recesses being adapted to receive the ribs 0f thefirst member, and Wings on the members for securing them to the elementsto be joined, the members being locked when the Wings are in line, thefirst member acting as a cover for the clasp When it is locked.

' In testimony that I claim the foregoing, I

have hereunto set my hand this 4th day of January, 1907.

IRVING MANDEVILLE.
